d183b975da Add genesis block hash to NetworkGraph
This changes adds the genesis block hash as a BlockHash to the
NetworkGraph struct. Making the NetworkGraph aware allows the message
handler to validate the chain_hash for received messages. This change
also adds the hash value to the Writeable and Readable methods.

50b348c4fa [router] Fix + test routing via next/last-hop hints only
We had code in the router to support sending a payment via a single
hop across channels exclusively provided by the next-/last-hop hints.
However, in updating the fuzzer, I noted that this case not only
didn't work, but paniced in some cases.

Here, we both fix the panic, as well as write a new test which
ensures we don't break support for such routing in the future.

d737111044 derive(Clone) for several pub simple data structs.
There is no reason not to and Clone can be useful especially in the
bindings context.

Replace ChainWatchInterface in NetGraphMsgHandler
ChainWatchInterface was intended as an interface for watching rather
than accessing the chain. Remove get_chain_utxo and add chain::Access
trait for this behavior. Wrap it with an Option in NetGraphMsgHandler in
order to simplify the error interface.

de8c5dc76d Use slices to references not slices of concrete objects in pub API
Because the C bindings maps objects into new structs which contain
only a pointer to the underlying (immovable) Rust type, it cannot
create a list of Rust types which are contiguous in memory. Thus,
in order to allow C clients to call certain Rust functions, we have
to use &[&Type] not &[Type]. This commit fixes this issue for the
get_route function.

edeb122ce5 Refactor route tests
* Splits up the monolithic test into smaller unit tests

* Factors out helpers for graph setup

* Changes `id_to_feature_flags` to be a function, there was no
reason why it had to be a macro

* Activates a previously commented-out test that checks for
the failure case in `disable_node_test`

4395b92cc8 Relicense as dual Apache-2.0 + MIT
This changes the LICENSE file and adds license headers to most files
to relicense under dual Apache-2.0 and MIT. This is helpful in that
we retain the patent grant issued under Apache-2.0-licensed work,
avoiding some sticky patent issues, while still allowing users who
are more comfortable with the simpler MIT license to use that.

See https://github.com/rust-bitcoin/rust-lightning/issues/659 for
relicensing statements from code authors.

Improve error message.
... for ChannelError and APIMisuseError
Before this commit, When rl returns error, we don't know
The actual parameter which caused the error.
By returning parameterised `String` instead of predefined `&'static str`,
We can give a caller improved error message.

TestLogger now has two additional methods
1. `assert_log_contains` which checks the logged messsage
  has how many entry which includes the specified string as a substring.
2. `aasert_log_regex` mostly the same with `assert_log_contains`
  but it is more flexible that caller specifies regex which has
  to be satisfied instead of just a substring.
For regex, tests now includes `regex` as dev-dependency.

bcd65bed7b Take &NetworkGraph as input in get_route, not a NetGraphMsgHandler
This was just an oversight when route calculation was split up into
parts - it makes no sense for get_route to require that we have a
full route message handler, only a network graph (which can always
be accessed from a NetGraphMsgHandler anyway).

ChannelManager+Router++ Logger Arc --> Deref
This caused a bunch of cascading changes, including
passing loggers down to Channels in function calls
rather than having each Channel have a pointer to the
ChannelManager's Logger (which was a circular reference).
Other structs that the Channel had passed its Logger to also
had their loggers removed. Other newly unused Loggers were
also removed, especially when keeping them would've caused
a bunch of extra test changes to be necessary, e.g. with
the ChainWatchInterfaceUtil's Logger.
